So in a player made level, cave johnson says that, "as of this morning, i have been resurrected as a computer!" This means that along with Caroline in GLaDOS' body, Cave Johnson is in a robot as well! I beleive that portal 3 is going to be all about cave johnson's robot is going to do something, or "awaken" from his slumber. (kinda like GLaDOS). But he is somewhere else in the laboratories. Leave a response to what you think.

NO ! that was cave from another paralel universe. don't you know what the idea of PeTI is? you are transported somwhere in the multiverse and there is another earth, another aperture and another cave jonson, where GLaDOS (and/or caroline) may even not exist. your theory sucks

we all know (well at least most people, anyway) that valve cant count to 3 although there are easter eggs that show hints about half life 3 and there is always the space core and wheatley they could fall back to earth and take over the world and also aperture science could always team up with black mesa (chell with portal gun and freeman with gravity gun) it would make an awesome co-op mode too!

If any of you have read the fanfiction "Blue Sky", you would see the proof that a Portal 3 can exist. In it, Wheatley comes back, and so does Chell. If Valve wants my advice, they should remake Blue Sky word-for-word into a game. I would call it Portal 3: Return to Aperture, or something.

They Probably made it so that people could make their own Portal 3, or whatever. [/b]

Yes, that is a good point; however, a sequel would not just need new tests to run through, it would also require character and plot development, new recorded lines [preferably by the original voice actors], a plot that would add to the overall playthrough of the game, and, naturally, more science to do.

maybye the serises is back wards like portal 3 is portal then portal is portal 2 and portal 2 is portal 3

This is a good idea. Perhaps it would help Valve steer away from main characters that don't talk. As everyone who's played Portal 2 knows, Chell was indeed at the "Bring your Daughter to Work Day" event; also, in Lab Rat, it is hinted that GLaDOS was first powered on at that time, when she took over the facility, killed off the scientists, etc. Maybe the third Portal would tell Chell's story, before GLaDOS, or while GLaDOS was turned on.

But If they were to make a portal 3 then it would be out in 2032 or something cus it takes a couple of years for games to come out (o_o)

This is true as well. Valve runs on Valve-time, which means that they can be counted on to release their games slightly after their announced deadline. If a Portal 3 were to somehow be created, assuming there was no leaks, it would come out around 2020-ish, if they began the work on it now. That's also assuming that the plot advanced during the game, and the length was similar.

They Probably made it so that people could make their own Portal 3, or whatever.

BUUUUUUT...

That would be cool, like you are a test subject from when Cave Johnson ran the place and tested for him. That would be EPIC!!!

I really like this idea, and I could only think of one thing: In the game, during the alpha gel part you have to take a detour from one test chamber to another... This is because there is a blocked door leading to a "time travel" experiment. I think that says all I wanted to say...

(Also, I think a great plot would be to be a test subject from Cave Era, and start travelling in time with this experiment, and learning a lot more about Chell's origins, GlaDOS attack and maybe -just MAYBE- finding a character from a previous game, either Chell from Portal 2 or Gordon from HL2 -or 3?- )
